Moss, sweating profusely, looked up and found that the person who was speaking was a teenage boy who didn't care much and continued to repair it. Seeing that the master ignored him, Nick tactfully looked for the information he needed.

There are indeed all the information in this library. He quickly found information about computers. What surprised Nick was that many computer books talked about a kind of thing called programming. What is programming? He didn't know, so he first found a book about computer introductions to read.

Holding the book introduced by this computer, Nick began to read it carefully and slowly watched it. He gradually dissolved into the world of computers. He began to learn that computers are electrical equipment used as digital calculations. In addition to high-speed calculations, their purpose also derives many data processing functions, such as the storage of data and data. All operations and data are completed by two numbers 0 and 1 in the computer, because in the world of electronics, there are only two states of on and off. If electronics are used to calculate, it must be simplified to 0 and 1 representing on and off...

The magic of computers made Nick's interest increase and expand in geometric multiples, as if the computer was part of his body, an organ. Only now did he discover that this new organ belonged to his body, he began to gradually understand, gradually master this organ, and activate this organ to let it perform its functions.

Nick sucked the knowledge in the book thirsty, and the way 0 and 1 seemed to be naturally in line with his thinking. This knowledge was engraved in his mind like a brand. In addition, he had a deep foundation in electronics before, and the knowledge about computer hardware made him more understandable and digestible. Soon, the book on computer basics had been translated, and he felt that these basic knowledge seemed to be born to let him know. As long as he read it once, he felt that he had known it for a long time.

Putting this basic knowledge back on the bookshelf, he took a starter from the operating system from the bookshelf. The basic knowledge introduced that to master the computer, you must first start with the keyboard layout. The keyboard layout is already in the basic knowledge, and you must be familiar with it and find opportunities to practice in the future. The second step is the operating system, which should be a bridge for human-computer communication. As long as you read a few pages, you have a deep understanding of the DOS operating system described in the basic knowledge. Nowadays, computers generally use DOS systems. DOS systems are a pure text system that controls the computer by inputting instructions. The book explains in detail the role of each command. Nick concentrates on these instructions and from time to time, he can't help but look at the computer in the library for a few glances, and his heart is full of desire to practice.

Before he knew it, a long time passed, and many people gradually came to the library. Although there were many people, everyone silently obeyed the rules of the library, so it was still very quiet. Suddenly, a scream broke through the tranquility of the library. Almost everyone looked at the place where the sound was initiated. Nick saw that it was made by Master Mos, and what made him feel furious was that Master Mos was staring at him with an alien look.

Nick took a small step back timidly. Master Moss seemed to have no eyes at all. He walked over and grabbed Nick's hand and dragged it to the projector. He said in shock: "0.13mm coil, 0.13mm coil, how do you know it is broken?"

Master Moss' sudden behavior made Nick panic and stuttered: "This, the light projected by the projector is yellow, the scanning frequency is relatively chaotic, and the peripheral edge light is periodically generated. This phenomenon will only occur if the signal feedback amplification distortion occurs..."

Old Moss looked at the boy in shock again. He really couldn't believe his eyes. Old Moss, as a professional maintenance worker, could understand these professional language. What made him feel extremely shocked was that repairmen as experienced as himself had spent half a day finding the fault with the help of a multimeter. This teenage child could determine the fault without any measuring instruments, and it was extremely accurate. It was really terrifying.

Old Moss recovered from some gods and continued to ask, "You, have you repaired a projector before?"

"No... I haven't repaired it, this... this is the first time I have seen this electrical appliance!" Nick told the truth. Projectors are naturally only available in science and education. How can civilian electrical appliances have such things?

This made Old Moss even more incredible. The circuits in the projector were also very complicated. I had never looked at the circuit diagram in advance to understand the principles, so I had no idea how to start. I had repaired the projector several times myself, so I naturally had some understanding of its internal structure and working principle.

Old Moss said in surprise: "How did you know that the 0.13mm coil is faulty

"Oh, from the functions of this appliance and the components on the circuit board, I already know the composition of its circuit. Looking at the components on the circuit board, you can find the signal feedback amplification part. The signal feedback amplification part has its own unique component arrangement. Look at the signal circuit above, it is composed of a double triode amplification circuit. In this part, it can be caused by this fault phenomenon, that is, the 0.13 mm coil."

Morse was stunned when he heard this. Just like this, you can see the circuit composition. This is like the legendary technology. The child said that the fault is correct, but the fault of the coil was found by measuring parts one by one, rather than like this child. It was simply a hit. Morse asked carefully: "Then did you repair the TV in the club yesterday?"

When asked this question, Moss was indeed very careful and he had not solved the fault. If it was repaired by this child, the technology would be too terrible. Although TVs are common electrical appliances, universal does not mean that their construction is simple. You can imagine how complicated the circuit workflow would it be to turn electrical signals into lively and extremely clear moving images? How does the TV turn electricity into images? Perhaps laymen can't imagine the working principle of the circuit of the TV.

"That TV has a big problem. After I watched you repair it, I suspected that it was a resistor because of the age of time, but it was not very certain. So after you left, I applied the resistor with a pencil through the case. The material of the pencil is conductive graphite. Applying it with a pencil on the resistor can increase its conductivity at will. I estimated the deviation of this resistor and applied it with an appropriate amount of graphite. I have not tried it if the TV has been repaired!"
